OK, I've bought the IR filter (Hoya R72) , so what special steps do I need to take now to shoot IR.

Before you say anything Markulous, I'll remember to attach the filter to the lens

First you need to buy my old Canon 10D. ('Cos it's more sensitive to IR than the 20D/30D. )

Next... Just put it on a tripod, use a decent lens stopped down a bit to avoid 'hot spots' and have a play. Focus manually - the correct focus won't be quite where the focusing scale shows. Exposure times can be very long.

Or... cheat and spoof it in Photoshop.

Far easier to do it in CS Dave........



Can't you send the filter back for a refund

More sensitive? I just have to remove the dust filter on my camera.......... which doubles as the IR filter. Instant IR!

I have just recently bought an R72 though much cheaper than Hoya. I have a EOS 20D which is not very sensitive to IR but is usable. I have tried experimenting and you need about 30 seconds exposure. It was a windy day so the clouds move a long way in 30 seconds, the wheat in the field also moved in the wind so only the barn stayed still. The result was everything in the frame except the barn was blurred. I will have another go soon on a day without wind.

Dave, you'll have to share your secret location of this barn if local

I hope I'm not going to burst your bubble here Dave but I hope you've still got your D70. If I remember correctly the D70 has a much weaker IR filter than the D200 giving it a much better IR capability. I was told not to bother doing IR images with the D200 as it is just not possible to get a decent image.

I'm sure a quick Google will throw up more info.

Sold the D70 whilst I could still get a decent price for it

Oh I don't know :- Infrared (IR) shots - Hoya R72 filter

[Dave]

One problem I am getting though is a "hotspot" in the very centre of shot that is over exposed all the time If i stop the lens down, the hotspot gets smaller. I'm sure I've read you should use a lens hood with the filter, but I thought that was only applicable if sunny day. These shots were taken in overcast conditions & still occured. Had to PS them out

Anyone else experienced that ?
